Studies have demonstrated an association between CHD and neurodevelopmental delay. This delay is associated with many factors like reduced blood flow and oxygen, cardiac catheterisations, and genetic factors. Apo E gene polymorphism is one of these genetic factors. This study aims to show the effect of Apo E gene polymorphism on neurodevelopmental process in children having CHD. A total of 188 children having CHD were admitted to the study. Apo E gene polymorphism of these patients was determined, and psychometric evaluation was performed. The relationship between psychometric test results and gene polymorphism was evaluated. This study shows that, similar to the literature, patients having cyanotic CHD have worse scores than acyanotic patients, and the children with CHD are under risk in terms of neuropsychiatric disorders. Other novel and important findings of this study were the lower verbal scores of ε2 allele carriers than ε4 carriers in Wechsler Intelligence Scale for Children-Revised group and the worse test score of patients having VSD than other acyanotic patients. Besides, some special disorders may be seen in this patient group.

Twin–twin transfusion syndrome (TTTS) is a severe complication of monochorionic (MC) twin pregnancies associated with high perinatal mortality and morbidity rates. Management in TTTS is a major challenge for obstetricians and neonatologists. Twins with TTTS are often born prematurely after an extremely distressing and highly hazardous fetal period. Follow-up studies report varying rates of cerebral palsy (CP) and long-term neurodevelopmental impairment (NDI). This review discusses the latest findings on the long-term outcome of TTTS survivors, possible risk factors for long-term impairment, and provides recommendations for future research.

Objective: The aim of this study was to compare the neurodevelopmental outcome at 12–18 months’ corrected age between multiples and singleton preterm infants. Methods: We designed a prospective study of preterm infants (≤32 weeks gestation) born and hospitalized in the neonatal intensive care unit between November 2008 and November 2009, whose assessments were performed at 12–18 months’ corrected age. Neurodevelopmental impairment was defined as the presence of any one of the following: moderate or severe cerebral palsy, severe bilateral hearing loss or bilateral blindness, mental developmental index score, or psychomotor developmental index score less than 70. Results were compared for both multiples and singleton infants. Results: One hundred and fifty-nine multiples and 211 singleton infants were assessed at 12–18 months’ corrected age. The neurodevelopmental outcome including all parameters at 12–18 months’ corrected age in multiples was not significantly different from singleton preterm infants. Conclusions: Multiple gestation in preterm infants is not associated with an increased risk of neurodevelopmental impairment at 12–18 months’ corrected age compared with singleton preterm infants. For further information, long term and high participation in neurodevelopmental follow-up and evaluation at pre-school age will be needed.

The objectives of this study were to determine compliance rate in a uniform, urban African-American patient population at environmental risk for adverse neurodevelopmental outcome and to define risk factors for non-compliance with neurodevelopmental follow-up. A retrospective chart review was performed which included 481 infants with birth weight (BW) of 495–4195 g and gestational ages (GAs) between 23 and 42 weeks born at our hospital. Statistical analysis was performed using the Jonckheere–Terpstra test for ordinal variables. For 2 × 2 tables, χ2 test and Fisher’s exact test (P < 0.05) were used. To determine significant predictive variables, data were analyzed by multiple logistic regression with one independent variable at a time. Infants compliant with follow-up had significantly more morbidities in the very low BW category (⩽1500 g) than infants with larger BW. The highest compliance rate (70%) was found among the smallest and most immature (GA ⩽28 weeks) infants. Based on this finding, we postulate that the number of infants with severe disability is not likely to be underestimated. The significantly more frequent developmental anomalies found in the largest BW (⩽2500 g) category raises significant concern, though findings in this subset of infants may not be representative of the whole population. There was no significant difference between the compliant and non-compliant groups regarding socio-economic status. Severe or multiple morbidities and prolonged hospital stay may provide parents with greater opportunity to learn and understand about the infant’s condition which may lead to greater compliance.
